FAIRMODEL

This well-known macroeconometric model is now available on the Internet. Virtually all the features of the stand-alone package are now accessible to any user free of charge. This includes the ability to "forecast, do policy analysis, and examine historical episodes." Data and forecasts can be both graphed and put into tables (which can be downloaded). It appears the model itself can be downloaded, and thus adapted for your own use. Both Fortran and EViews versions are available.

The U.S. version of the model is rather complex (131 equations in all; 101 identities and 30 stochastic equations), it is highly recommended that users read the manual before using it. Extensive documentation (in fact, much material similar to "Testing Macroeconometric Models," Ray Fair, Harvard University Press, 1994) is available. One can also read about the latest forecasts of the model. To use FAIRMODEL, you must have a browser that supports Java and frames.

In addition, the multicountry (MC) model is available as well. It covers the U.S. and 32 other countries. In all, there are some 4,000 variables, not counting the trade share variables (which can be downloaded). It is thought to be "one of the largest computational problems that has so far been offered on the Internet."
